A Receptor-like Pseudokinase in Stomatal Closure
Research, The Plant Cell, The Plant Cell: In a NutshellSierla et al. show that GHR1 is a receptor-like pseudokinase that acts in stomatal closure through its scaffolding functions rather than by directly phosphorylating its target proteins. Plant Cell https://doi.org/10.1105/tpc.18.00441.

A Root Endoploidy Map: The Spatial and Temporal Arrangement of Dividing and Endocycling Cells
Research, The Plant Cell, The Plant Cell: In a NutshellBhosale et al. computationally predicted and experimentally verified the DNA ploidy level of all cells in the Arabidopsis root tip, revealing that endoreplication is spatiotemporally regulated, stress-responsive, and likely important to coordinate cell expansion with changes in cell wall structure. Plant…
